Hello all. I have a question about a problem I'm trying to prevent from happening again.
Here's my background information:
A basement water pipe that leads to a frost-free sillock froze and burst. It's a walkout basement and the pipe runs from the sillock up the interior basement wall to the ceiling joists. There is a cutoff valve in the ceiling joist. (which I unfortunately neglected to close this winter) The basement was finished into living space a few years ago. The insurance adjuster determined the root cause of the problem to be the fact that the insulation was placed on the wrong side of the pipe when the basement was finished. That is, the pipe was located on the cold side of the insulation instead of the heated space side. (Closing the additional cutoff valve would have been a good idea too. )
What I've done:
1. Upgraded the leaking cutoff valve with a ball-valve.
2. Replaced the frost free sillcock hose bib with a new unit, which is apparently also anti-siphon. (The old unit was getting difficult to turn) My original sillcock was not anti-siphon. The new (B&K Mueller) one is anti-siphon. (Apparently it's now required).
My question:
I've noticed that even if I turn off the shutoff valve in the ceiling joists, the anti-siphon "feature" of the sillcock won't allow the wall pipe to drain. It drains the sillcock, but the remaining wall pipe does not drain. This seems like a problem. Is this normal? It seems that this anti-siphon "upgrade" may be worse in my particular case. Is there something else that I should do to drain the wall pipe?
Thanks for any help!
